Product Description
Combining a compact footprint with top-tier hardware durability, this Micro ATX motherboard is constructed on a premium moisture-resistant high-density glass fabric PCB reinforced with 2oz copper layers. It integrates an 8-phase digital power design utilizing premium 50A power chokes and a massive XXL aluminum alloy heatsink to preserve excellent thermal stability under load. Outfitted with a full-coverage metallic solid-state storage heatsink, a triple monitor layout interface, and full system surge protections, it delivers excellent multi-screen handling, audio clarity, and high equipment responsiveness.
Key Features:
- Heavy-Duty Thermal & Power Infrastructure: Outfitted with an 8-phase digital power delivery layout, heavy-duty 50A chokes, and a massive XXL aluminum alloy heatsink stack to maintain cool thermal operational zones.
- Condensed Expandable Layout: Streamlined Micro ATX size tailored for compact chassis builds while sustaining 4 memory slots with premium 15μ gold plating contacts.
- Native Triple Display Support: Provides three independent video output alternatives (analog D-Sub, HDMI, and DisplayPort) to drive up to three monitors simultaneously.
- Full-Coverage Storage Cooling: Features an integrated full-coverage metallic armor heatsink on the primary M.2 slot to eliminate data bottlenecking from thermal throttling.
- Full Spike System Safeguards: Implements active built-in electrical guards across all critical rear panel connections (USB, Audio, LAN) to protect sensitive components against voltage spikes.
